Hypothesis
Can a two-dimensional omnidirectional wireless power transfer (OWPT) system effectively power capsule robots in various spatial orientations?
Conclusion
The proposed OWPT system can provide a stable power supply of at least 550 mW with a voltage fluctuation rate of 7.68% across different positions.
Supporting Evidence
- The system achieved a minimum received voltage stability of 94.5% across different positions.
- An experimental prototype demonstrated the ability to provide a minimum received power of 550 mW.
- The design accommodates patients of various body types, enhancing usability.
Takeaway
This study created a special power system that can send energy to tiny robots inside the body from many directions, helping them work better.
Methodology
The study involved designing a two-dimensional OWPT system, optimizing coil structures, and conducting experiments to test power transfer efficiency.
Limitations
The large size of the transmitting structure may affect user mobility and comfort.
